what's happened?

she has done a terrible mistake

what mistakes?

teacher Lin changed the time of handing in the final exam, Katy then tried to upload a new file again...

but! with other's ID since she was using another computer!!!

so she did not upload her file? I can not understand oh my english is poor

she uploaded her previous file with her ID before 11:45, and uploaded a new file with another student's ID before 12:00

那怎麼辦?

she tried to find Lin, however, it was lunch time... and I don't know what happened after that...

she asked me to email to her, but she did't promise that she will see it
